(Bill Bradburry) ________________________________ Message 1 _____________________________________ Time: 12:22:24 AM PST US Subject: Re: AeroElectric-List: Crankcase ferrous particle detectors? From: Peter Pengilly Some helicopter mag plugs also have a high current connection to burn 'fuzz'. A mag plug warning from the main (or tailrotor) gearbox is a 'land immediate' or 'land as soon as possible' event, so false alarms have serious consequences - helicopters scattered all over the country side. If the warning is due to a large chip indicating a gear or bearing is breaking up then its done its job. But if its due to a collection of small particles - or fuzz - then no one's very impressed. The plugs can be pulled regularly and cleaned, but that just adds to the servicing cost. Alternatively using a high current in the chip detector circuit means the fuzz doesn't cause (so many) false alarms. My experience is that most false alarms occur within the first few hours from delivery - or perhaps that is just a reflection on the quality standards of 1990s military suppliers...

From: Bill Allen Roger wrote <> Bob was correct, a "breaker" in The Queens vernacular would be a "salvage yard" in Americish - a quick google search turns up many of them and White Industries have been going since Pontious was a pilot. The type I used (from an R22 gearbox) is a simple plug with magnetic contacts which are normally open, but should metallic debris bridge the contacts, will complete a circuit. It looks very much like (and could well be) this; http://www.allenaircraft.com/products/chip_detectors.html and I got it from: http://www.nalsonaviation.com/ in the UK - aircraft spruce used to sell them, but its no longer listed on their website. I have it connected to a Dynon Skyview so that a red warning will come on, and a press-to-test button to check it's working. In a helicopter, a main rotor gearbox failure is analogous to the wings coming off an aircraft ie; if the main rotor gearbox starts shredding itself, it wont glide/autorotate as a fixed wing aircraft will, hence the higher imperative to reduce false alerts. Many cars have magnetic sump plugs, and it will be seen that they often have a covering of "fuzz" (rather than chunks of metal) which are the microscopic particles of normal wear held in a yogurt-like paste around the magnetic probe. Another feature of the part from the R22 is that it is easily removable, being a 2 part component with a self-sealing mechanism to allow the electrical probe to be removed without the contents of the sump coming with it. Peter was correct, - usually false alarms occur within the first few hours of a rebuild as the "fuzz" flushes through held in suspension in the oil, cumulatively settling out overnight to the lowpoint where the detector is installed. I fitted it because I have installed an engine which is unusual and does not have millions of in-service hours behind it. On a Lycoming/Continental it's probably not worth it unless you really are involved with your engine. Some people don't care much between annuals and 50 hr oil changes. I am the opposite and go with SOAP ( eg; http://www.spectro.in/Spectrometric-Oil-Analysis.html ) and 25hr oil changes. Having a good EIS and a chip detector is just another tool in my quiver against premature engine failure. I realise that the original question from Eric has been over-answered, and for this I apologise :^) Bill Allen LongEz160 N99BA FD51 CZ4 G-BYLZ EGBJ LongEze Diesel G-LEZE EGBJ On 17 October 2014 21:29, wrote: > > > I don't know the original source of these when new, but they're affordabl e > from the breaker. > > at the risk of sounding stupid, may I ask, who is =9Cthe breaker =9D? > > Roger > > -- ________________________________ Message 3 _____________________________________ Time: 05:52:49 AM PST US Subject: AeroElectric-List: Re: Strange characters From: "user9253" I do not know what causes the strange characters.

I am guessing that Bob has the book and that I will get that along with other documentation for the project when I pick it up. I did try to go to the links on you sire but for some reason could not access the downloadable pdfs I will try again, and also the links to Bob's architecture are gone because his site is no longer active. If you have copies and could send to me that would be interesting reading for me. I thank you for your help with understanding this and I think your first suggestion of starting over may be the ticket. I just feel sticking as close to the KISS principle is often a good decision. I will have enough to do without complicating my flight demands .

If you are savvy enough, you can change to setting in Outlook to send in plain text only, but it is not an easy change to find. The reason everything looks fine in Outlook is because it is set to receive what other Outlook users send. Most other email programs give you a choice of what fype of formatting to send. Problems arise with email listserv transmissions because they usually strip off most of the html encoding to conserve space.

A friend has been fighting high oil temps for several months on his O-320. The last flight he saw a sudden drop in temp followed a few minutes later by a spike which went away and the temps were then fine for the rest of the flight. I thought that the oil cooler bypass might have been stuck and then opened but the temp dropped too fast I think for this to be a real temp change. It seems to me that it may be instrumentation. He is also having obvious instrumentation problems with EGT#1. It is very erratic. I hope some of you can give him a few ideas as to how he can troubleshoot these problems and hopefully get them resolved. Here is a link to a Savvy Analysis data dump that he made on the last flight. https://www.savvyanalysis.com/flight/741039/7be0f496-4815-45d2-9eee-4455fc4f 5e98 Any ideas would be appreciated.
